Abstract: Multi-phase motors are gaining more attention due to the advantages of good fault tolerance capability and high power density, etc. By applying dual-rotor technology to multi-phase machines, a five-phase dual-rotor permanent magnet synchronous motor (DRPMSM) is researched in this paper to further promote their torque density and fault tolerance capability. It has two rotors and two se...

Fault tolerance is an essential methodology for digital systems, particularly for those that serve applications where failure has safety implications or where interruption of operations imposes serious financial penalties. There is no single fault tolerance technique that suits or is optimal in all circumstances. A taxonomy of fault tolerance techniques is presented and branches and leaves of t...

We focus on the problem of synthesizing failsafe fault-tolerance where fault-tolerance is added to an existing (fault-intolerant) program. A failsafe fault-tolerant program satisfies its specification (including safety and liveness) in the absence of faults. However, in the presence of faults, it satisfies its safety specification. We present a somewhat unexpected result that, in general, the p...

Fault tolerance is becoming an increasingly important issue, especially in mission-critical applications where data integrity is a paramount concern. Performance, however, remains a large driving force in the market place. Runtime reconfigurable hardware architectures have the power to balance fault tolerance with performance, allowing the amount of fault tolerance to be tuned at run-time. This...

The relevance of Byzantine fault tolerance in the context of cloud computing has been questioned[3]. While arguments against Byzantine fault tolerance seemingly makes sense in the context of a singlecloud, i.e., a large-scale cloud infrastructure that resides under control of a single, typically commercialprovider, these arguments are less obvious in a broader context of the Int...

In a grid environment there are thousands of resources, services and applications that need to interact in order to make possible the use of the grid [1] as an execution platform. Since these elements are extremely heterogeneous, volatile and dynamic, there are many failure possibilities, including not only independent failures of each element, but also those resulting from interactions between...

for the yearbook This thesis describes adaptive multi-dimensional fault tolerance as a network service in Programmable Networks. We outline the concept of a component based programmable node architecture. Based on this performant and fault tolerant plattform we introduce scalable fault tolerance as a transparent network service. The foundation of the service are cooperating transparent overlay ...

The DTS (Dependability Test Suite) fault injection tool can be used to (1) obtain fault injection-based evaluation of system reliability, (2) compare the reliability of different applications, fault tolerance middleware, and platforms, and (3) provide feedback to improve the reliability of the target applications, fault tolerance middleware, and platforms. This paper describes the architecture ...

A Theory of Fault-Tolerance Components1 Anish Arora Sandeep S. Kulkarni Department of Computer and Information Science The Ohio State University Columbus, Ohio 43210 USA Abstract In this paper, we show that two types of tolerance components, namely detectors and correctors, appear in a rich class of fault-tolerant systems. This class includes systems designed using the wellknown techniques of e...

Traditional modular redundancy based upon software fault tolerance techniques, such as N-version programming and recovery blocks, is now widely known and its use is on the increase. By contrast, data fault tolerance techniques have been largely ignored. The most likely reason for this omission is the perception that implementations are highly complex. Fortunately this situation has been greatly...
